Tokenized Money Market Funds as Settlement Cash and Collateral

Among the assets that have actually moved on chain at institutional scale, tokenized money market and short duration treasury products stand out. They are often presented as a tokenized investment, a way to hold a familiar low risk product in a new form. That framing understates what is happening. Institutions are adopting these products primarily for a use that has little to do with holding them: as settlement cash that earns while it waits, and as collateral that can move on shared infrastructure.

This matters because it changes the questions that should be asked. An investment is judged on what it returns and what it risks. A settlement asset is judged on whether it is available when needed, whether it can be moved cleanly, and how it behaves when many holders want out at once. A collateral asset is judged on whether it can be pledged and mobilized and on how reliably it can be valued. The tokenized money market product is being asked to do the second and third jobs, and those jobs expose a tension that the investment framing hides.

The tension is this. The token transfers continuously, at any hour, the way a settlement and collateral instrument should. The fund behind the token does not. It is a regulated fund with the mechanics of one: it values itself at set points, it processes dealing at set times, and it carries the liquidity fees and redemption gates that funds use to protect themselves and their holders under stress. A continuous instrument sits on top of a discontinuous one, and the gap between them is where the operational risk lives. This report examines that gap, why these products are held as cash and collateral, and what it takes to use them in those roles without being caught by the fund machinery underneath.

To understand the risk, start with the appeal, because the appeal is genuine and explains the adoption. A tokenized money market product combines two things institutions value and rarely get together: a place to hold cash that earns a return close to short term rates, and an instrument that lives on shared infrastructure where it can be moved and used programmatically.

As settlement cash, this is attractive because cash held for settlement usually earns little and sits idle between uses. A tokenized money market holding lets that cash earn while it waits, and because it lives on the ledger, it can in principle move into a settlement at the moment it is needed rather than being funded in from a bank account on a separate clock. The holder gets a yield on balances that would otherwise be dormant and a settlement instrument that is native to the infrastructure the assets settle on.

As collateral, the appeal is mobility. Conventional fund interests are clumsy collateral, slow to pledge and slow to move. A tokenized holding can be pledged and transferred on the ledger with the speed of any token, which makes it usable in arrangements where collateral must move quickly and frequently. For an institution that needs to post and recall collateral across counterparties and venues, an instrument that earns a return and moves like a token is a meaningful improvement over a static fund position.

These uses are why the category has grown, and they are entirely reasonable. The point of this report is not that the appeal is false. It is that the appeal is real enough that institutions adopt these products for cash and collateral roles before fully reckoning with the fund mechanics that those roles will eventually run into. The benefits are visible immediately. The mismatch shows up later, usually under stress.

The grid sets the mechanics of the underlying fund against the expectations that a continuously transferable token creates, and names the gap between them. Each row is a place where the token and the fund are running on different clocks.

Read down the gap column and the theme is one clock against another. The token runs continuously and the fund runs periodically, and every row is a consequence of that single difference. The instrument works smoothly while the two clocks happen to agree and reveals its seams when they do not.

A tokenized money market product is a regulated fund with a token wrapper, and it inherits the full apparatus of the fund. That apparatus exists for good reasons, and understanding why it is there explains why it cannot simply be discarded to suit the token.

A fund values itself at set points because valuing a portfolio is an exercise that happens at a moment, against prices struck at that moment. The valuation point produces the price at which units are created and redeemed, and it is the anchor for everything the fund does. A fund deals at windows with cut off times because processing subscriptions and redemptions in batches, against a struck valuation, is how a fund maintains fairness between the holders coming and going and the holders staying. These mechanics are not arbitrary friction. They are how a pooled vehicle treats its participants consistently.

The liquidity tools matter most for this report. Money market funds in particular have, in many jurisdictions, the ability to apply a fee on redemptions or to gate redemptions entirely under stressed conditions. These tools exist precisely because a money market fund can face a wave of redemptions in a crisis, and allowing everyone to exit instantly at an unadjusted price would harm the holders who remain and could force the fund to sell assets into a falling market. The fee and the gate protect the fund and its holders by slowing or pricing exit when exit would otherwise be destabilizing. They are a feature of prudent fund design, and they are written into the rules of the product whether or not it has been tokenized.

The token does not remove any of this. It cannot, because the machinery belongs to the fund and the fund is still a fund. What the token does is create an expectation that sits in tension with the machinery, and the work of using these products well is the work of holding both the token and the fund mechanics in view at once.

The core of the problem is that a continuously transferable token sits on top of a fund that operates in periods. This is not a flaw in either layer. It is a mismatch between two designs that were sound on their own and now have to coexist.

Consider valuation. The fund strikes a value at set points. The token transfers at every point in between. So for most of the time, a holder transferring the token is transferring a claim whose value is not being struck at that instant but was struck at the last valuation point and will be struck again at the next. In a stable money market product this is usually a small matter, because the value moves little between points. It is not nothing, and in a period of stress, when the value between points can move more, transferring against a stale valuation carries a risk the continuous token quietly invites.

Consider dealing. Secondary transfer of the token, holder to holder, can happen at any time. But creating new units or redeeming units against the fund itself happens only at the dealing windows. So the token has two different liquidity profiles depending on what a holder is doing. Moving a position to another holder is continuous. Getting cash out of the fund is periodic. A holder who conflates the two, who assumes that because the token transfers at any hour they can also turn it into ordinary cash at any hour, has misread the instrument. The secondary market in the token may or may not be deep enough to absorb their exit at the moment they want it, and the primary route through the fund is only open at certain times.

Consider settlement. Token transfer is immediate, but redemption proceeds from the fund settle on the fund's cycle. A holder who redeems is not paid the instant the token is burned. They are paid when the fund settles the redemption, which follows the fund's calendar. The immediacy of the token applies to moving the holding, not to converting it back into spendable cash through the fund. Each of these is a specific instance of the same general mismatch, and each is manageable once it is understood and dangerous when it is assumed away.

The collateral use deserves its own treatment, because it is one of the strongest reasons institutions hold these products and it interacts with the fund mechanics in particular ways.

As collateral, a tokenized money market holding has a real advantage: it can be pledged and moved on the ledger, which makes it far more mobile than a conventional fund interest. In arrangements where collateral must be posted, recalled, and substituted frequently, this mobility is valuable, and an instrument that also earns a return while it sits as collateral is more capital efficient than cash that earns nothing. For these reasons tokenized money market products are being used as collateral in a growing range of arrangements.

The mechanics of the fund shape how that collateral behaves. The value of the collateral, for margining and for any close out, depends on the fund's valuation, which updates on the fund's schedule. Between valuation points the collateral is being marked against a value that is not currently being struck, which is usually fine for a stable product and matters more in stress. If the collateral must be liquidated, the same dealing windows, settlement cycles, and potential liquidity fees and gates apply. A counterparty relying on being able to convert pledged tokens into cash quickly under stress is relying on the fund's redemption mechanics holding up under exactly the conditions those mechanics are designed to slow.

This does not make tokenized money market products poor collateral. It makes them collateral whose behavior is governed by the fund underneath, and a collateral arrangement built on them needs to account for the fund's mechanics in its valuation, its margining, and its close out assumptions. The mobility is genuine and the value reference is periodic, and a collateral framework that uses these instruments well respects both rather than treating the token's mobility as if it extended to the fund's redemption.

Everything in this report converges on a single scenario: a period of stress in which many holders want out at once. This is the situation the fund's liquidity tools were built for, and it is the situation in which the mismatch with the token is most dangerous, because stress is when expectations and mechanics collide hardest.

In normal conditions, the gaps between token and fund are small and rarely tested. Values move little between valuation points, secondary transfer absorbs ordinary exits, and the liquidity tools sit unused. A holder treating the token as instant cash usually gets away with it because nothing forces the difference to the surface. Stress changes that. In stress, more holders want to redeem, values can move more between points, and the fund may do exactly what its rules permit: apply a liquidity fee to redemptions, or gate them. A holder who has been treating the token as instant, full access cash meets a fee that reduces their proceeds or a gate that delays their exit, and meets it precisely when they most wanted certainty.

Nothing improper has happened. The fee and the gate were always in the rules, and they exist to protect the holders as a group from the damage of a disorderly rush for the exit. But a holder who adopted the token as settlement cash, attracted by its continuous transferability, may never have internalized that the cash they were holding came with a fund's stress mechanics attached. The continuous token told one story and the fund's rulebook told another, and stress is when the rulebook wins. The institutions that use these products safely priced the gate and the fee into their plans from the start, treating the instrument as a fund that happens to move like a token. The ones that mistook mobility for guaranteed access find the fund underneath at the moment they most need the access to be real.
